Abstract
A liquid crystal display electronic watch comprises a metal substrate, whose upside and downside surfaces are insulated by a flexible print sheet. A liquid crystal cell and a time keeping decoder drive circuit are arranged on the upside of the substrate and other circuit elements are arranged beneath the downside thereof. The exteriorly operating parts are arranged around the periphery of the substrate. All of the electrical and mechanical operating members are arranged in a plane with respect to the substrate and so electrically connected and mechanically interlocked that date and/or week day are displayed with the least possible members. The watch is thin, small, simple in construction and reliable in operation.
